• Developed and tested various C++/Python OOP features for NVIDIA Omniverse Isaac Sim robotic simulation platform.
• Discovered then bugfixed C++ sensor data persisting in buffers on restart of simulation and added absolute orientation quaternion output for IMU sensor. Also updated pybind Python interface.
• Used OmniGraph Python API to create drag-and-drop graph nodes that acquire and forward sim data from IMU and Contact sensors.
• Devised pytest tests to verify accel/gyro/orientation and contact sensor corner cases using sample robots.
• Unit tested differential base robot assets to expose odd caster wheel behavior and attempted fixes.
• Authored an instructional tutorial for the Read IMU OmniGraph Node and verified in collaboration with QA.
